A plug-and-play ripple mitigation approach for DC-links in hybrid systems [PDF]

, 2016
© 2016 IEEE.In this paper, a plug-and-play ripple mitigation technique is proposed. It requires only the sensing of the DC-link voltage and can operate fully independently to remove the low-frequency voltage ripple. The proposed technique is nonintrusive

AAA+ protein unfoldases—the Moirai of the proteome

FEBS Letters, EarlyView.
AAA+ unfoldases are essential molecular motors that power protein degradation and disaggregation. This review integrates recent cryo‐electron microscopy (cryo‐EM) structures and single‐molecule biophysical data to reconcile competing models of substrate translocation.

Adaptive resonant frequency tracking of piezoelectric transducers based on variable universe fuzzy PI control [PDF]

Nanotechnology and Precision Engineering
As the power core of ultrasonic instruments, the piezoelectric transducer generates a strong impact force when operating at resonance. However, the influence of various uncertainly applied payloads on the electrical characteristics of piezoelectric ...

Transcriptional network analysis of PTEN‐protein‐deficient prostate tumors reveals robust stromal reprogramming and signs of senescent paracrine communication

Molecular Oncology, EarlyView.
Combining PTEN protein assessment and transcriptomic profiling of prostate tumors, we uncovered a network enriched in senescence and extracellular matrix (ECM) programs associated with PTEN loss and conserved in a mouse model. We show that PTEN‐deficient cells trigger paracrine remodeling of the surrounding stroma and this information could help ...

Highly sensitive frequency metrology for optical anisotropy measurements

, 2010
In this paper we present a novel apparatus aimed at measuring very small birefringences and anisotropies, based on frequency metrology and not on polarimetry as usual.

Remote power control strategy based on virtual flux approach for the grid tied power converters [PDF]

, 2018
The control of active and reactive power for the Renewable Energy Sources (RES) based power plants are very important. The injection of active and reactive power to the grid is normally controlled at the Point of Common Connection (PCC) where this point ...

Proportional-Integral and Proportional-Resonant Based Control Strategy for PUC Inverters

IECON 2018 - 44th Annual Conference of the IEEE Industrial Electronics Society, 2018
In this paper, a proportional-integral (PI) and proportional-resonant (PR) based control strategy is proposed for packed-U-cell (PUC) inverters. In the conventional PI-PI based control strategy, while the first PI regulates the DC capacitor voltage, the second PI regulates the AC load current.
